LAVATORY FIXTURE. I APPLICATION FILED SEPT-19,1114.

Patented Aug. 6, 1918.

I VZ/M5 includes the usual body or casing 1 having eoperationwith theerown/liandle'as herelos'etlie tubular portion of theb'earing head aycitizen of the .United States, residing atr 'Be it knownthat I, EARLChicago, Cook county, Illinois, have invent- 4 ed certain new and usefulImprovements inA Lavatory-Fixtures, of which the 'following is aspecification.

My invention relates to a lavatoryffixture and the object thereof is toimprove the construction and operation of suclrxture, particularly thoseof the type in which the valve is normally held closed-by springpressure and opened againstsucli pressure. My invention consists more,particularly in the,

provision of vnovel and simple means for locking the `valve 'steiii'andadjusting nut in" adjusted position and also in the provision of noveland simple cam means for operating the valve by means of the usual crownhandle and for preventing the sticking of the handle which frequentlyoccurs in fixtures o'frthis type.` rThe various features of 1 advantageand utility in my new constructionvoflavatory fixture will be apparentfrom the de scription hereinafter given. I

the action ofthe ballsin riding upwardly upon the inclined cam surfacesof theI grooves 6a. Inasmuch as the valvestem is operatively connectedf* with the crown haii dlev in the manner hereinafter explained, thevalve will be opened. n

TheY crown 'handle can be operated in Veither direction, that isb-yturning to the right or tothe left, but it is desirable that meansbeprovided for limiting the niovefn ment of such rhandle in eitherdirection and one featuieof. my invention relates to such means'. yThestops 6b,`lierein beforereferred to,` are three in number correspondingto theA Y number of cam groovesandrballs employed and any two o f themare adapted'to coper ate with the single stop 7d formedon kthe exteriorAof the Vcylindrical portion of the crown handle .and locatedintermediate two ofthe grooves 7C. When the partsarein normal positionthefstorfi'?d is locatediinidwa'y betweentwo of the stops 6b, with theresult that when thehandle isturiiedin one direcf" tion theV stop 7dwill contact one" of these two stopsv 6b and when .turned in the 'otherdirection it will contact the other stop 6b.

They stopsy 6b" arearranged at the end of radial lines passing throughthe center of the grooves 6` so that, when the' crown handle isturne'dand tlielstops arein con-VV tact, the handle has reached'its eXtremeposi?v tionV of oscillation and 'cannot be oscillated any lfartherbyreason of the positive stopping means thus provided.Vv Heretofore whenno positive stops were. employed and reliance wasplaced 'uponlthe'ends`ofthe grooves 6a! for stopping purposes, the-balls would ride uponthe intervening space between the grooves 6a and would stick"thereon-,with the result that the valve would `be held open and thewaterV permitted to waste. Y

vThe cylindrical portion of vthe crown handle is provided with a centralcircular recess into' which the outer end of the yvalve steine extendsand which receives the adjusting nut9; n By preference/balls 10 actingas bearings are provided between the nut and the bottom ofthe recessoff/the crown handle.v The nut screws uponfthe screw-threaded end of thevalve whereby the position oi the stem and its valve relative to thehandle may be adjusted and provision thereby made for the proper seatingot the valve in case of wear. valve stein and crown handle are held inproper relativeV position by means of` the coiled spring 11whichnorinally holds the valve seated.

The adjusting nut and valve stem are providedl with' means tor lockingthem together, constituting another feature of my invention. madetubula1 at its outer end to receive a coiled spring 12 and such end isprovided with diametrically opposite slots 5l". The adjusting nut has acentral counterbore opening, thelarger of which is screw threaded toscrew upon the screw threads of the outer end of the valve stem and the'vid-ing shoulders 13 on its opposite edges.`

The narrower portion ot this plate extends i'ipwardly through thesmaller bore of the nut and into the slot 9b thereof. This plate isheldl projected in such normal position as shown in Fig. 1 by means otthe coiled spring lVhen in such position the plate locks the adjustingnut and valve stem together, that is prevents any rotation of the nutthat would destroy the said adjustment. lllheinhowever, it is desired tomake .a new adjustment the construction is such that the locking deviceis unlocked as an incident to the act of applying,v a tool such as ascrewdriver to the nut and turning the same. TWhen the screw-driventorinstance is insertedr in the slot 9b of lthe nut it necessarily contactsthe upper end ot the locking plate 13 which is thereby forceddownwardly7 against the tensionA of its spring. lllhen the plate hasthus been depressed below the planel of this slot the nut is tree to beturned in the proper direction toradjustment purposes, and when the toolis removed from the nut and the latter is in such position that its slot9B will register with the slots 5a thelocking plate will at once beprojected outwardly to locking position by means of its spring. Thelocking plate 13' is limited or stopped in its upward projection bymeans of the contact between its shoulders 13 and theinterior shoulders9Z1 of the nut. lt will be understood that the cavity or recess of .thecrown handle is closed by the removable plug 14.

By reason of the provision of the stop stem TheA Yin` the ordinaryconstruction.

l As shown the valve stem is iueiubcrs G" and l the movement of thecrown handle in both directions is limited, thereby preventing anybinding or wedging action of the balls such as frequently occurs lVhenthe parts are in normal` position the stop member 7d" ismidway betweentwo adjacent stop members G" so thatthe handle may be oscillatedl ineither direction but stopped when the member 7d comes in contact witheither one of said two adjacent stops 6b. By the provision of threeeqi'iidistantly spaced stops 6b the crown handle in being assembledmaybe placed in any one of three positions so thatfits stop member 7dlwill be positioned between any two of the three stops 6b.
